Shallow Sump Options

For vessels with very limited space between the engine, bearers and hull we can offer a specially designed shallow sump option. The key differences are a reshaped sump pan and repositioning of the sump pump connection.

Oil volumes are marginally reduced (please refer to relevant operators manual) but the dip stick calibration is unchanged. However when this option is fitted, it is important to note that the frequency of the oil change period is reduced. Rather than the standard oil change hours of use, engines fitted with a shallow sump require an initial change after 50 hours then either annually or every 150 hours if sooner.

Beta 10 to Beta 25

Special Feet Service

Beta Marine engines have been fitted into tens of thousands of vessels around the world using our standard engine feet. However engine bearers can vary immensely so when a problem arises, our solution is to offer our unique service of designing and manufacturing “Special Engine Feet” to suit your individual engine bearers.

Having designed, manufactured and supplied thousands of bespoke “Special Feet” when required, the additional cost of this option is heavily repaid when your new engine just drops onto your existing engine bearers and lines up with your propeller shaft reducing installation complexity, time and labour.
